The game is in the alpha stages, but progress is very, very rapid. Alpha 14 is the version that'll be on the cover disk; a new Alpha build is released every month, and there are nightly development builds for the very enthusiastic.

Please, do try it out. We're all extremely proud of our work, and we're dead excited that it's going to get some extra exposure!

Awesome. You should be well proud! I totally love Frontier, so a free, portable, graphically modern implementation is a dream come true. I know there's still a lot of work to be done, but it has so much potential. When I get some spare time, I'll try to join in the bugfixing and development effort.
